IMPROVEMENTIN HAY-CARRIERS.

The Schedule referred to in thmietten Patent and making part of the same.

To all whom it may concern .in a condition for being moved upon the suspension beam.

Figure 3 is a section taken vertically and. transversely through the center of the device.

Similar lettersof reference indicate corresponding parts in the several figures;

This invention relates to improvements which are designed to facilitate the use of hay-elevating forks or slings in the operation of transferring hay from wagons into barns.

The nature of my-invention consists First, in a truck-frame, which is sustained by and adapted to travel on a beam or a stretched rope, and which is provided with a gravitating catch, adapted to engagethe truck with ashoulder on the suspendingbeam or rope, and which is also supplied with a trippingdevice, which is applied on the elevating-rope, and which will disengage the said catch from the said shoulder when the load has been elevated to a proper height,

and allow the load to bemoved to the required position for discharging it, as will'be hereinafter described.

Second, in so combining a gravitating catch, a ropebrake, a pulley, and a tripping-plate with a truckframe that, simultaneously with the movement of the catch to release the truck from a shoulder on its suspension-beam or rope, the elevating-rope will be tightly clamped and held against the pulley on said truckframe, thereby preventing the elevated load fromdescending as the truck-frame is moved along, as will be hereinafter explained.

Third, in the application of a tripping-plate loosely on the elevating-rope, in combination with a truckframe, and a device which will engage such frame at a given point with the suspension-beam or rope, as will be hereinafter explained.

To enable others skilled in the art to understand my invention, I will describe its construction and operation.

In the accompanying drawing- A represents a strong beam, which should be sustained near the peak ot' a barn into which hay is to be stacked.

B represents a truck-frame, which is sustained upon said beam by means of ,the wheels aa, so as to travel freely in a direction with the lengthof the beam.

At the lower end of the truck-frame, and centrally arranged, is a grooved sheave, b, over which passes the elevating-rope B, which rope also passes through a tackle-block, 0, arranged at any desired point, and attached to the beam A, or any other object.

Two arms, ,0 c, are applied'rigidly to the truck-frame B, and to the lower ends thereof a gravitating catch,

. G, is pivoted, the rear curved end 9 of which is loaded, so as to preponderate over the hooked end g.

Above the catch G a gravitating brake, h, is pivoted to the arms co in such relation to and above the sheave b that the loaded or longest end of this brake will lie upon the rope B on said sheave, when the truck-frame is disengaged from the block D,an d thereby prevent the load from descending, as shown in fig. 2. D is a block, which is secured to the lower edge of the beam A, and which is so shaped as to leave a shoulder at d for receiving the hooked end g of the gravitating catch, as shown in fig. 1.

Block D is alsomade with a curved or inclined surface, c, against which the shortest arm of the brake h abuts, when the truck-frame is engaged by its catch G with the block D, as shown in fig. l.

The'block Dis arranged over the pointfrom which the hay is elevated, and it serves, in conjunction with the catch G, to hold the truck-frame B in one place on the beam A during the act of velevating the loads.

' J is a circular plate, the upper surface of which is preferably convert, and through the center of which a hole is made for receiving loosely through it the elevating-rope B. v

This plate J is slipped on the rope B between the. sling or fork, as the case may be, and thesheave b, so that, when a load is elevated to the highest pointdesired, said plate J willpress up the end g of the catch G, release the hooked end of this catch from block D, and thus allow the truck-frame to be moved along with the suspended load toward the tackleblock C.

At the same time that the truck-frame is moved away from the block D, the longest end of the brake It will-drop upon the rope B on sheave b, and thus prevent the load from descending.

When a load has been discharged from a suspended sling or fork, and the truck-frame or carrier drawn back over the wagon again by means of the pull-cord attached to the sling or fork, the catch G will engage with the block D, and at the same time the brake h will be disengaged from the rope, thus allowing the latter to run down for a repetition of the operation.

It will be seen from the above description that the loads of hay can be elevated perpendicularly from a wagon to the peak of the roof of the barn, and then moved horizontally to a position for discharging the loads; also that these results are obtained by a very simple combination of devices which are substantial and not liable to derangement.

It is obvious that a stretched rope may be employed instead of the suspension beam A, for sustaining the truek-liame or carrier, in which case two grooved wheels would be substituted for those marked a a; but I prefer to use a beam as described, on account; of its stiffness.

I do not claim broadly, under this petition, the combination of hay-carrier with an elevating apparatus. Neither do I claim broadly the employment of a looking device with a carrier and elevator, as such devices are shown and described in Letters Patent granted to me on the 26th day of January, 1869.

What I do claim as new, and desire to secure by Letters Patent, is-- 1. The bracket or arm 0, with the gravitating or self-locking catch G g g, applied on or formed upon the pulley, truck, or carriage B, in combination with the blockl) d, substantially in the manner described.

B J, for elevating hay, in the manner and for the purpose described.
